Pd-incorporated polyoxometalate catalysts for electrochemical CO 2 reduction

We investigated the electrochemical CO 2 RR performance of a Pd-incorporated polyoxometalate ([H 2 SiW 10 O 36 Pd 2 (OAc) 2 ] 4− ) possessing various countercations on a carbon electrode and found that the Ba 2+ salt exhibited selective CO production over 12 h.
